IMPROVEMENT IN SHEEP-SHEARING CHAIRS.

Specification forming part of Letters Patent No. 3 61,622, dated April6, 1875 application filed February 5, 1875.

. To all whom it may concern:

Be it known that we, CHARLES H. MoGALL and JAMES H. MoOALL, ofMorristown, in the county of Belmont and State of Ohio, have inventedcertain new and useful Improvements in Sheep-Shearing Chairs; and we dohereby declare that the following is a full, clear, and exactdescription thereof, which will enable others skilled in the art towhich it pertains to make and use the same, reference being hadto theaccompanying drawings, and to the letters of reference marked thereonwhich form a part of this specification.

Our invention relates to improvements in that class of devices used forholding sheep during the process of shearing. It consists in a seat,concave or otherwise, rigidly attached to the floor or shearing-table;in an adjustable platform, slotted to fiton the shank of the seat, andrevolving entirely around the latter; and in slotted uprightadjusting-boards, sliding upon stationary standards, and to which ishinged the rack for holding the sheep, the whole constructed andarranged as hereinafter fully set forth.

In the drawings, Figure 1 is a rear vertical elevation. Fig 2 is a planView, with the hinged rack and seat removed; and Fig. 3 is a sideelevation of our invention.

a is the floor or shearing-table. b is the seat on which the sheep isset. It is made concave, as shown, or of any desired form. It isconstructed with a short shank or foot, which rests on the floor andholds it above the revolving platform, hereinafter described. It isbolted or otherwise rigidly fixed to the floor a, so that the sheep whenplaced thereon will remain in the same position during the entireprocess of shearing, unless changed by lifting and turning on the seat.The revolving platform, hereinafter described, enables the shearer toget in any desired position, with reference to the sheep, to facilitatethe clipping and avoid lifting. c is the revolving platform, to which issecured the several adjusting devices hereinafter described. It ispierced at one end by the oblong mortise 0, through which the shank ofthe seat b passes, andit revolves on said shank. The slot ormortise 0permits the setting of the rack, hereinafter described, farther off ornearer to the seat, as desired, to accommodate the device to larger orsmaller sheep. c is a rod, held by staples across the mortise c andagainst the shank of the seat, so as to prevent the platformfrom slidingback and forth when such result is desirable. d is an upright board orstandard, extending across and tenoned in the revolving platform, nearthe center of the latter, and near to the edge of the seat I). Itinclines slightly away from the seat, and is provided with the verticalslots or mortises d d. e is an adjustable frame. It is placed in frontof and slides up or down on the board d, and is secured to the latter bythe bolts 6 6 passing through the slots cl d. It can be set at anydesired position by said bolts and slots. f is the rack or rest on whichthe sheep is held. It is hinged to the top of the frame a by the rod fand can be set at a greater or less incline by the regulating-brace). gis an upright board or standard, placed at the rear part of theplatform, and longitudinally with the latter. It is tenoned intheplatform, and provided with the vertical slots g g. h is an adjustableframe, secured to the board 9 by set-bolts h h It has secured to it thestirrup or clevis h through which passes the brace f the latter beingprovided with suitable ratchet and spring to hold it in proper place.z'is a connecting rod or brace, which unites the frame c with the frameh. It secures a corresponding movement in and perfect adjustment of thetwo frames 6 and h and the rack f. It also supports the frame 6, andprevents the latter from being strained when set high for large sheep.Suitable straps, for use by boys, may be attached to the rack f and seatI), by which the sheep can be bound to the device.

The sheep, having been placed on the seat in the position desired forcommencing the clipping, is not changed during the entire process. formis revolved, so as to bring the rack into different relative positionsto the sheep. The labor of lifting the animal is avoided. To get therack in a different position under the sheep, the latter is pushedforward sufficiently to take the weight off the former, when theplatform is turned, so as to bring the rack to As the clippingprogresses the platthe desired place, and the sheep is again laidthereon. The platform turns away from the fleece, and the latter turnsdown off the sheep, and remains in an almost undisturbed condition untilthe clipping is completed. Thus the tearing or breaking of the fleece isprevented, a result unattainable, except by the greatest carefulness, indevices where the seat revolves to adjust the sheep to the rack.

Having described our invention, what we claim, and desire to secure byLetters Patent, 1s

1. The revolving platform 0, in combination with the stationary seat 11,substantially as and for the purpose specified.

2. The combination of the adjustable frame e, with the rack f, revolvingplatform 0, and seat b, substantially as and for the purpose set forth.

3. The combination of the adjustable frame h and braced, with therevolving platform a, frame 0, and rack f, substantially as and fo thepurpose set forth.

In testimony that we claim the foregoing as our own we hereto affix oursignatures in presence of two witnesses.
